IMPROVEMENT IN EJECTOR-CONDENSERS.

Specification formingr part of -Letters Patent No. 178,434, dated June6, 1876 application tiled February 17, 1876.

. To all whom it may concern Be it known that I, J AMES F. GUTHEIE, ofSomerville, in the county of Middlesex and State of Massachusetts, haveinvented a new and useful Improvement in Ejector-Gondensers, of whichthe following is a specification:

This invention relates to ejector-condensers, which are used to condensethe exhaust steam from steam-engines, and entirely dispense with theair-pump; and the invention consists of a peculiar construction andcombination ofparts, which will be fully. hereinafter described, andspecifically pointed out in the claim.

In the accompanying plate of drawings, Figure l represents a verticalcross-section of an ejectorcondenser having my improvements attachedthereto; Fig. 2, ahorizontal cross-section on lille x x, Fig. 1; andFig. 3 is a horizontal cross-section of the water-conduction tube online y y, Fig. 1.

A in the drawings represents an ejectorcondenser, of which B is theinlet for steam U, the inlet for water; D, the discharge-pipe, and E theinduction-tube; Iand F, the conduction-tube for the passage of the waterafter it hasenteredatinletOto thecombining-chamber Gr; H, the plug inconduction-tube F, to regulate the liow or quantity of water, all asordinarily in ejector-comlensersnow in use, and therefore needing' nofurther description herein. I is the discharge-nozzle ofconduction-.tubeF. This discharge-nozzle I is formed substantially as shown, and isadapted by a screwthread, a, to be screwed on or oli' of conduction-tubel".

When the steam in the ruiming of the engine is ot' a high` pressure atthe point of exhaust, for a complete and effective action of the waterupon the steam in -the working of the condenser, a larger surface ofwater must be exposed in the combining-chamber for contact with thesteam, and, obviously, when the steam is at a lower pressure at theexhaustpoint, a corresponding decrease of the surface of the water isnecessary.

The discharge-nozzle I, in its position as shown in the drawing, isadjusted for a high pressure of-steam at the exhaust-point, exposing tothe steam a greater surface of the column of water passing through thecondenser, as the end b of discharge-nozzle I is at a greater distancefrom the bottom of combining-chamber, and when the steam at the eX-haust point is at a low pressure, by unscrewing the discharge-nozzleaccordingly as the steam is more or less of alower pressure at theexhaust-point, the discharge-nozzle can be adjusted to the requirementsof the ejectorcondenser, as is obvious.

' L, an opening or hand-hole in the casing at d of the condenser, andcovered b v the cap M, which is adapted to be readily removed whendesired.

To adjust the discharge nozzle I to its proper work through the openingor handhole, a rod or wire can be inserted into one of' the holes, c, inthe periphery of dischargenozzle I, which can then be easily turned toits proper adjustment.

Bythe use of this hand-hole L, the breaking otl joints ot' the condenseris avoided, and the discharge-nozzle can be adjusted without interferingwith its operation or the running of the engine. n

In adjusting the discharge-nozzle I to the pressure of steam at theexhaust-point, the plug H is also accordingly regulated to maintain thesa mequantity ot'water passing through discharge-nozzle.

N is a stuffing-box, to prevent leakage of steam or water through thejoint a ot' discharge-nozzle I and conduction-tube F, which wouldinterfere with the working of the condenser.

' This improvement is applicable to condensers for steam-pumps, and alsoas well to injectors of boilers; but when used in injectors, the pipesconnecting with the injector must be arranged so that the steam willenter inlet C, and the water inlet B.

I am aware of the patent to Robinson and Gresham, dated May 29, 1866,and I disclaim the construction therein shown.

Having now described my in 7ention, what I claim, and desire to secureby Letters Patent, isfl In an ejector-condenser, having the handopeningL and conductor-tube F, the adjustable discharge-nozzle I, having therecesses c, by which it is adjusted through the handopening L,substantially as described.

The above specification of my invention signed by me this 31st day ofJanuary, A. D. 1876.
